Part of a the $70 million major upgrade project to improve traffic flow on the 33-year-old crossing over the Fraser River, an extra seventh counter flow lane will be made possible through a moveable, zipper-like barrier system for the peak hour traffic.
A system similar zipper barrier system is on the Golden Gate Bridge in San Francisco.
The province today announced that an additional lane is now open on the bridge.
Four lanes are available for southbound traffic, with three lanes remaining for northbound.
Meanwhile, work continues on the intelligent transportation signs needed for the counter-flow operation, and the ministry expects the zipper truck-barrier transfer system to be in place later this fall.
More than 119,000 vehicles use the Alex Fraser Bridge daily on average, with road users experiencing lines more than three kilometres long during rush hour.
The George Massey Tunnel and Lions Gate Bridge also use counter flow lanes but those are controlled by movable gates.
Dress rehearsal - "Road Zipper" style. Before the #AlexFraserBridge moveable barrier system is put in place, along with an additional 7th lane, we're ensuring operators are well trained. #DeltaBC #RichmondBC pic.twitter.com/vtwjmHVzNw
